CAL DC POWER

12V to 20V

CONDUCTIVITY

ELECTRODE

TEMPERATURE

• Press the COND/TEMP key to display conduc-

tivity readings and select the appropriate

conductivity range

e.g. "19.99 mS" for HI7030/HI8030,

"99.9 mS" for HI7034/HI8034,

"1999µS" for HI7031/HI8031,

"199.9 µS" for HI7033/HI8033.

• Using a small screwdriver adjust the trimmer on the rear panel

until the display shows the conductivity reading at the tempera-

ture of the solution noted earlier (see the

conductivity vs. temperature chart on page

13) e.g. "11.19 mS".

Calibration is now completed and the instrument is ready for use.

TO CHECK THE CALIBRATION

• Press the COND/TEMP key to display the tem-

perature.

• Adjust the TEMPERATURE knob to display the

temperature of the calibration solution, i.e.

the temperature noted with the CHECKTEMP

or glass thermometer.
